The value of X is:<br> A 11.3<br> B 8<br> C 16

diamong [38]

Answer:

x ≈ 11.3

Step-by-step explanation:

Using the sine ratio in the right triangle

sin45° = $\frac{opposite}{hypotenuse}$ = $\frac{8}{x}$ ( multiply both sides by x )

x × sin45° = 8 ( divide both sides by sin45° )

x = $\frac{8}{sin45}$ ≈ 11.3

{2x + 3y = 5}{ y= 5 x -4}

Natasha_Volkova [10]

Solve the system using substitutions:

$\begin{gathered} 2x+3y=5 \\ 2x+3(5x-4)=5 \\ 2x+15x-12=5 \\ 17x=5+12 \\ 17x=17 \\ x=\frac{17}{17} \\ x=1 \end{gathered}$

x has a value of 1. Use this value to find the value of y.

$\begin{gathered} y=5x-4 \\ y=5\cdot1-4 \\ y=5-4 \\ y=1 \end{gathered}$

y has a value of 1.

x=1

y=1

Vertical : Angles 1 & 4 Supplementary: 5 & 6

Step-by-step explanation:

Vertical angels are angles that have the same measure that are opposites of each other (1 & 4) and supplementary angles are 2 angles that equal 180 degrees that are right next to each other or right above each other (5 & 6) (3 & 5)
